SCREEN.

Specification of Letters Patent.

Patented Nomd, 1910.

' To on whom may concern:

Be it known that I, JOHN B. HOAGLAND, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Screen, of which the following is a specification.

This invention relates more particularly to the frame of the screen, and its object is to provide an improved joint for the corners thereof.

The invention also has for its object to provide a joint by which theframe sections can be readily assembled by unskilled persons.

Another object is to provide a joint which is strong and which results in a rigid frame.

With the foregoing objects in view the invention consists in a novel construction and outer edges of the stiles are grooved as usual, to receive the slides.

The wire cloth, or other screen fabric 'or material which is indicated at 7, is secured to the frame by extending it at its edges into grooves'8 made in the face of the stiles and rails, and in which grooves it is held by strips 9 driven thereinto, the screen being thus securely held between the strips and the walls of the grooves. In making the frame, it can be either mitered, or cut square at'the corners.

so as to bring the grooves together. The screen frame herein described is of that type known as a knock-down frame, the stiles and rails being fastened together by corner. fastenings which will now be described.

The corner fastening comprises a sheet metal-plate consisting of two branches 10 and'll, respectively, extending at right angles to each other. A plate as herein described is fastened to each corner of the frame by means of nails, brads or other suitable fastening means 12. The branch 10 is secured to the rail, and the branch 11 to the adjacent stile, the width of said branches being slightly less than the width of the rail and stile, so as to permit the latter to be trlmmed to properly fit the window or other frame. Each branch of the plate is formed with a bead 13- made by,bend1ng the plate, which beads extend into the grooves Y 8, the bead of the branch 10 fitting in the groove of the rail, and the bead of the branch 11 fitting in the groove of the stile. The beads clamp the corners of the screen fabric in the same manner as the strips 9. The strips, however, may be continued through the channels formed by the beads so that the appearance of the frame may not be marred.

At the inner edge of the corner plate is a flange which fits the inner angle of the frame. This flange extends at right angles to the corner plate and is formed on each fastening devices are adapted to be driveninto the frame. I

By means of the'corner fastening herein described, the stiles and rails can be readily assembled and fastened together, and they will hold the frame square and rigid. The corner fastening is preferably made of a single piece of sheet metal which is stamped into the shape.shown,,in view of which it can be cheaply produced.

The bead 13 not only secures the corners of the screen fabric, but also serves to stiffen the plate, and to assi'stin holding it in place.

What is claimed is:

The combination with a wooden screen frame having a grooved face, of a corner fastening com rising an an ular sheet metal plate fitting t e frame at t e corners thereof, and spaced at its outer edge from the outer edge of the frame to permit trimming of said edge, said plate having a bead entering the groove of the frame, and a flange projecting from the inner edge of the plate at an angle thereto, said flange fitting in the inner angle of the frame.

In testimony that I claim the foregoing as my own, I have hereto atfixed my slgnature in the presence of two witnesses.
